Two basic types of chemical straighteners
- A.
Guanidine hydroxide and sodium hydroxide
- B.
Guanidine hydroxide and lithium hydroxide
- C.
Guanidine hydroxide and ammonium thioglycolate
Correct Answer
A. Guanidine hydroxide and sodium hydroxideExplanation
The correct answer is Guanidine hydroxide and sodium hydroxide. These two chemicals are commonly used in hair straightening products. Guanidine hydroxide is a strong alkali that breaks the disulfide bonds in the hair, allowing it to be reshaped. Sodium hydroxide, also known as lye, is another strong alkali that works in a similar way to guanidine hydroxide. Both chemicals are effective in straightening hair, but they can also cause damage if not used properly.Rate this question:

Which emollient is most frequently used to base the scalp and hairline before a sodium hydroxide or lye relaxer is applied
- A.
Tea tree oil
- B.
Mineral oil
- C.
Petroleum
Correct Answer
C. PetroleumExplanation
Petroleum is the most frequently used emollient to base the scalp and hairline before applying a sodium hydroxide or lye relaxer. This is because petroleum acts as a protective barrier, preventing the relaxer from coming into direct contact with the scalp and hairline, which can cause irritation and damage. It also helps to minimize the potential for chemical burns and scalp irritation during the relaxing process. Tea tree oil and mineral oil are not commonly used as emollients in this context.Rate this question:

The most frequently noted side effect from using chemical relaxer is
- A.
Hair breakage
- B.
Hair growth
- C.
Hair knotting
Correct Answer
A. Hair breakageExplanation
Chemical relaxers are used to straighten curly or kinky hair by breaking down the protein structure of the hair. This process weakens the hair strands, making them more susceptible to breakage. Hair breakage is a common side effect of using chemical relaxers because the hair becomes fragile and prone to splitting or snapping. This can result in noticeable hair loss and a decrease in overall hair volume. It is important to take proper care of relaxed hair to minimize breakage and maintain its health.Rate this question:
